HOLDBACK FOR VEHICLES.

SPECIFICATION formingpart of Letters Patent No. 228,006, dated May 25, 1880.

Application filed September 22, 1879.

To all whom it may concern:

Be it known that I, JOHN D. WADKINS, of Oharlottesville, in the county of Hancock and State of Indiana, have invented certain Irnprovements in Holdback Attachments for Yehicles, of which the following is a specification.

My invention relates to holdback attachments wherein a metal holder is attached to the strap which is attached to the breeching, said holder being held and released by means of a spring-catch incased in a boxing attached to the shaft of the vehicle, as hereinafter fully described.

Figure 1 is a plan view of the holder. Fig. 2is a longitudinal vertical section with the holder removed.

A is the holder, provided with the recess B. This holder is passed into the mortise U and under the lug D, projecting downwardfrom the spring-catch E. The upper side of the spring-catch E is provided with a lug, upon which the spiral spring F rests.

The boxing or casing H H, which carries the spring-catch E and spring F, is recessed into the shaft of the vehicle and held in place by means of wood-screws, as shown in Fig. 2.

The lug D on the spring-catch E is raised out of the recess B in the holder by pressing on the handle I when it is desired to release the holder.

There is a piece of tin or other sheet metal, K, soldered onto the front end of the casing to cover up and hide the front view of the spring and spring-catch.

There is a bolt or rivet, L, which passes through the sides of the casing and through the spring-catch.

Thus it will be readily seen that to couple the attachment the holder A is pressed into the recess 0 and under the lug D of the springcatoh E, the spring F holding all inplace until it is desired to detach the holder from its fastenings, when a light pressure on the handle I releases it.

It will be seen from the construction that the harder the pull on the holder the harder the spring-catch is drawn downward into the recess B of the holder, since the tendency of a backward pull is to draw the lug D downward, as the lug is below the horizontal line of the rivet L; but when it is desired to release the holder it is readily done by means of a slight pressure on the handle I, and by this means I secure both great safety and great convenience by means of an inexpensive mechanism.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The casingH H, attached to the shaft of a vehicle and carrying the spring-catch E, provided with the lug D, spring F, and handle I, and vibrating on the rivet L, in combination with the holder A, substantially as shown and described, for the purpose specified.

JOHN D. WADKINS.
